Good to know before you book

All boiler service bookings are subject to a mandatory 30-day waiting period from the date of purchase before an appointment can be scheduled. You have a 14-day right to cancel for a full refund, provided no appointment has yet been booked - once an appointment is booked, this right no longer applies. A £60 missed appointment fee may apply if the engineer cannot gain access at the agreed time. Full details are in the Terms & Conditions above.

What is a boiler service, and how often do I need one?

Your boiler is probably the hardest-working appliance in your home, providing heat and hot water all year, yet it's often the most neglected. A boiler service and operational safety check help protect your household against the risk of carbon monoxide, keep the boiler running efficiently, and can save money on your heating bills.

We recommend booking a boiler service every 12 months. A Gas Safe registered engineer completes the service on a date agreed with you, once the applicable waiting period has passed.

What happens during your boiler service

Your Gas Safe registered engineer works through a thorough inspection to keep your boiler safe and efficient.

Visual inspection

A full check of the boiler, casing and installation for signs of problems.

Seals check

Inspecting seals to confirm the combustion is sealed and safe.

Flue gas analysis

Measuring the flue gases to check the boiler is burning cleanly and efficiently.

Gas pressure check

Confirming the gas is at the correct working pressure for safe operation.

Controls tested

Checking the thermostat, timer and safety controls all work correctly.

Corrosion & leaks

Looking for corrosion or leaks that could affect safety or reliability.

Carbon monoxide is the silent risk

Frequently asked questions

What is a boiler service?

A boiler service involves a Gas Safe registered engineer inspecting and maintaining your boiler to help ensure it's safe, efficient and functioning correctly. It typically includes a full safety check of the boiler and controls, inspection for leaks or corrosion, cleaning of key components, flue and ventilation checks, pressure and flow testing, and a service report.

How much does a boiler service cost in the UK?

The cost of a boiler service in the UK typically ranges from around £90 to £140, depending on the boiler type, your location and the provider. Smart Cover offers a boiler service from £99, or a boiler service with a CP12 landlord gas safety certificate from £119. Prices include all relevant taxes.

Why is an annual boiler service important?

An annual boiler service helps keep your boiler running safely and efficiently. Key benefits include:

  • Safety - helping guard against carbon monoxide risks
  • Efficiency - a serviced boiler tends to run more economically
  • Longevity - servicing helps extend the boiler's lifespan
  • Warranty - many manufacturers and insurers require annual servicing to keep warranties valid

What's included in a standard boiler service?

A standard Smart Cover boiler service includes a boiler inspection, seals check, flue gas analysis, gas pressure check, testing of all controls, and a corrosion and leaks check, followed by a service certificate. All work is carried out by Gas Safe registered engineers.

How often should I get my boiler serviced?

Annual boiler servicing is recommended for safety, efficiency and to help maintain your warranty. Most manufacturers and insurers require an annual service, and many boiler cover policies will not pay a claim if the boiler has not been serviced in the last 12 months.

What is a CP12 certificate?

A CP12, also known as a Landlord Gas Safety Certificate, is a document confirming that the gas appliances in a property have been checked and are safe. By law, landlords must have gas appliances checked annually by a Gas Safe registered engineer. Smart Cover offers a Boiler Service & CP12 option from £119that includes this certificate, valid for 12 months.

What is the difference between boiler cover and a boiler service?

A boiler service is a one-off inspection and maintenance check that keeps your boiler safe and efficient. Boiler cover is an ongoing insurance protection plan that includes repairs and emergency call-outs if your boiler breaks down, subject to policy terms, conditions and limits. Many people combine both - a service to prevent problems and cover to protect against breakdowns.

Can I get a boiler service near me?

Yes. Boiler services are available across the UK through a nationwide network of qualified, Gas Safe registered engineers. Call 03333 449 559 to book a service on a date that suits you.

Why is the red light flashing on my boiler?

A flashing red light usually indicates a fault such as low pressure, ignition failure or a sensor issue, and some models flash during a reset cycle. It should always be checked by a professional. If you hold boiler cover, you may have access to 24/7 support and call-outs, subject to policy terms and limits.

How do I book a boiler service?

You can book a one-off boiler service by calling 03333 449 559 . A Gas Safe registered engineer will be arranged to complete the service and operational safety inspection on a date agreed with you. A boiler service may also be included in some home emergency cover plans, depending on the level of cover.

How soon can my boiler service appointment be booked?

All boiler service bookings are subject to a mandatory 30-day waiting period from the date of purchase. No appointment can be scheduled until this period has fully elapsed.

Can I cancel my boiler service booking?

You have the right to cancel within 14 days of purchase for a full refund, provided no appointment has yet been booked. Once an appointment is booked, no refund applies. A £60 missed appointment fee applies if the engineer attends but cannot complete the service for reasons within your control.
